It doesn’t matter how many edgy “theories” people try to make–Mario and Luigi are supportive, caring Good Brothers all throughout the history of the canon.

Like… so many things have been retconned to there and back again, like the Brooklyn origins of the bros, their last name, or the nature of the Koopalings’ relation to Bowser…

But that Mario and Luigi are the best, supportive sibling team has never been retconned or questioned.

In Level 6-9 of Super Mario Bros. 3, it is possible to skip the entirety of the level by using a glitch to jump over the wall at the start. If Small Mario jumps towards the wall, touches it at exactly the right pixel and the A button is pressed again, he will perform another jump in mid-air and have enough height to get to the top of the wall. From there, going to the right will lead directly to the end of the level. Warning: there is an unseen Koopa Troopa on top of the wall that may kill Mario, so it is best to keep jumping to avoid touching it. (Source)
